Get the bell engraved, I had the bell engraved and it's helped it stay in my possession. Also i took an empty vial made a label with my name. Then stuck it off in vial, used nasal cannula tubing to create a loop around the chest piece. After that it hasn't walked off since and surprisingly I have been notified a few times after I've left in the box, on a scene and helps spot it in the hands of the illustrious stethoscope thieves aka nursing home techs.

MuchoMasQueMusculo saidHave you thought of a DIY project for something cheap?

HHAHAHAHAHAHA. I love it!!Once I developed my 'ears', it didn't matter what I used, even the disposable ones for ISO PTS worked fineMines an old Litman Lightweight, the aluminum bell doesn't swing up and smack ya when ya lean over like the heavy bells do Those angled ear pieces get caught on everything tho, annoying
